'lhenco the circuit passes through conductor a, boil (1, and wire I to the line-wire 1) to the switch S, thence by the wire 0 tothc bell lfl by the wire a and branch p to the switch l thence by wire to the battery and by wire 1' to switch 1*", and thence by the wire HI, to wire 1/ to button, closing the circuit thrt'mgh the bells in the cab of thcengine and'in the car, and it the latter bell rings the conductor knows he has operated the bell in the engine.

it. will be understood that the conductor or other person can send any prearranged code of signals which will be understood by the engineer. Now supposing the engineer dc- \Ve will sup sires to signal the CUHHLlULUl' or other person on thettrain, the switch S is moved from the terminal ot' the wire o to the terminal of the wire 1/1 and the button y/ is closed, completing the circuit between the wires 11 and n at lows: From the button g','througl 1 (L to the switch I), which is normally closed at this point through .r, the bell wire 1', line 1), through the switch S to the wire in, thence through the switch F, wire r to battery B, wire q to switch F, and through wires p and u to button This operates the bells in the ears without operating his own signal-bell.

bells operated by a direct circuit I may make use of relays and locateircuits for operating the bells, as is usual in telegraph systems, and such arrangement is shown in Fig.1f2. In this diagram l'ill" are the main batteries, either one of which mav be connected in cir euit by means of the switches l 1*", and A A are the batteriesot' the local or relay circuits,

cuit by the switches G t. The magnet E is in the main circuit; and closes the circuit to the local magnet- E". The bell is shown as an ordinary trembly-bcll,lnlt connected so that it maybe operated either as a single- -strol o hell or as a trein'bly-bell, according to the circuit elosed through the magnet.

Supposing the conductor or other person in the ear desires to signal the engineer, the push-lnitt.on-l) is pressed, closing the circuit l/yllll'OllQlllllO wire or, (the direction of this cir' cnit being indicated by a single arrow-heath) to the relay-magnet lfl, thence by the wire a to the switch h, thence by the wire l to the switch l ,vthence by the wire (1 to battery 13', thence by the wire 1' to the switch i and thence by the wire 11 and wire 1', through the coilsof the magnet, to the push-button. The local circuit may be traced from the relay through the magnet lC', (being indicated by a doublepointed arrow,) through the conductor a to the switch G, conductor 0*, battery A, conductor c, switch (1, conductor a" to a portion point ot starting. Iiijthis way the bell at the enginc will sound and the bell in the car will give :a single stroke, indicating that the relay in the engine operated correctly and closed the local circuit to give the signal to the engineer.

New, supposing the engineer desires to signal to the train, as before he moves the switch S to the terminal a, and the circuits (indicated by the triplc-hcadtnl arrows) are as follows: l rom the switch'S, through the push-button y, (if it; should be used, although which in this instance is connected to one of the terminals of the trembly -bell, thence through the armature c, the magnet-wire 'v to the conductor 7), and thence to the switch i thence by wire 1- to battery B, wire (1 to the button, and the circuits will betas fol-.

it isa push-button connected with a testcircuit by which the engineer can determine whether the battery is in operating condition or not, and by pressing this button 71 the circuit indicat'ed by the four-pointed arrows passes through the relay-magnet: l5", switch 1', battery 13, switch i and back to the push-button h; as will be clearly umler stood. V

Such being the general arrangement of the system, I wiil now describe the coupling devices by which the three wires of the cable can be connected between the cars and other portions of the circuit. Such device is fully illustrated in i igs. 13 to consists of two portions 1 and l of some insulating material, upon which are mounted the sprin s and connections for the wires onpoint and extendingmeyond the body 1. On

tering the ends, indicated, each portion being a duplicate of the other, so that they are interei'iangcable, no matter which ends of the cars COiflO together. The conductor m, for instance, enters through a. plug '13 and passes up through the body and is connected to the main spring 4 of the connector. This spring is provided atv its end.

with an enlarged portion 5, tapering to a the opposite side of the body 1. is another spring 6, having an enlargement 7, and to this the other wire t1, coming through the plug 3, is connected in the same way. site terminals of the conductors are connected to the main springs t3 9 oi the other portion 2 of the coupler in the same way. Also mounted on the body 1 at ninety degrees from the main springs are the plates 10 ll 12 1;

"and these are titted in recesses in the blocks and are of the form shown in Figs. 31 and 32. The free ends of these plates are" bent shown at; 1 1, and fit in a rcpess 15 in the center of the blocks, and normally the terminals 14 of the plates 10 and 11 and ,l. and 13 are respectively in contact. The other ends of the plates are formed in the shape best shown in Fig: 231 to constitute a key or signal device 16, which is arranged so that its free end is normally in contact; with the fixed portion of one of the main springs, as t, so that the circuit, from 4 is closed through the portion 16 to the plate '10 and from the opposite main spring 6 through. the plate 11, thereby forming a closed terminal to the circuits '1: an when the coupler is apart. Thesa-me istrue of the other terminals of the conductors Z) m in the portion of the coupler, the terminals of the plates 12 and 13 beingin contact at the points 14. \ihen, however, theparts of the coupler are put in position, as shown in 'higsjlt, 1(5,

and 18, the main springs i and t3, respectively, make electrical contact with the plates I2 and 13, and themain springs 8 and 9 make contact with the plates 10 and 11, and at the sametime the wedgeshaped portions 17 of The coupler O of the portionl The oppo- This wiii the couplers force the terminals ll apart, :breaking the closed circuits at these points, )and it results that the ends oi wires m. and the ends of wires h at each side oi the couplerare connected together by two paths, outg ior instance, being through the main spring i, extension 5, and plate 152 to the key 1 to main spring h, plate l0, key 16, and 73 again to the plate 4. In this way I insure good contact, for, it' perchancc, anything intcrrupts one path the other is likely to be free. More than that, this arrangement fnrnishes a means of signaling at the coupler, So

for by pressing both of the keys 1t) and 18 simultaneously the current through the conductor n1 is interrupted, and again by pressing both of these keysand the complementary keys connected with thc'conductor l) (which are the same in every respect as those previously described) both circuits can i be opened and. the coupler disconncetedwithout sounding an alarm. The third conductor o passes-plug 23 and is divided, shown in Fig.

lit, and connected to the plug 21 and socket 22, and the other terminal in the portion 2 is similarly connected to the plug 23 and socket 2-1. These plugs and sockets are preferably iorined as shown in detail in Figs. 25 to 28, 5

and when the portions 1 and 2 of the coupler are brought together the plug 21 enters socket E34 and the plug 2 3 enters socket 2'3, and the points in the sockets cnterthe opcningsin the endsot' theplugs,and thereby agootl electri calegntact isinsured. Itwill thus be seen that all thrceot' the conductors u, b, and or have duplicate paths or connections between the two portions 1 and 2 of the coupler, and when toothus joined. signals maybe sent by operating the keys of thecouplers, and when the por tions of the coupler are separated the circuits in and b are autonmtically closed, while the circuit- (0 is open. I

In order that the keys 1t; and 18 may be retained in close contact with the respective springs, I insert a block of rubber 30, 'hig. 24,

under each key in a recess inqthe block.

The terminals of a and i) are normally closed by the rod (Z; but when the button (Z is pressed the contact between (Z and a is broken and the circuit is closed through m and I). The plug (Z projects through metal plate (1, and

is supported by an elastic diaphragm r1 bc I2 5 neath the plate, and which normally holds it out of contact with the arm (I and serves to protect the contactsfrom extraneous matter. The button is prete'ral'ily protected by a hinged cover (1 Having thus described my invention, what I claim as new, and desire to secure by Letters Patents, is-
